Patented July 5, 1932 UNITED STATES PATENT OFFICE OF CINCINNATI, OHIO, ACORPORATION OF OHIO DOUGH WORKING DEVICE Application filed May 9,

This invention relates to an auxiliary dough molder adapted for use inconnection with a primary dough molder of any approved type, forexample, such as is disclosed in my co-pending application for a doughmolder filed February 24, 1925 and serially numbered 11,086.

An object of this invention is to provide an auxiliary dough moldingdevice provided with positive means for efiecting discharge of a moldedloaf from a primary molder to an auxiliary molder.

Another object is to provide means for the purpose stated, which issimple and effective.

These and other objects are attained by the means described herein anddisclosed in the accompanying drawings, in which:

Fig. 1 is a side elevational view of the device embodying the invention.

Fig. 2 is a plan view taken on line 22 of Fig. 1 showingdiagrammatically the rela tionship of parts.

Fi 3 is a side elevational view of a modified form of the device of thisinvention.

Fig. 4 is a plan view taken on line 44 of Fig. 3 showingdiagrammatically the relationship of parts.

The device of this invention comprises a frame 7 provided with suitablebearingsS and 9 which receive shafts 10 and 11 respectively, upon whichare rotatably mounted conveyor rolls 12 and 13. In each embodiment ofthe invention, the frame 7 is provided with an adjustable pressure board14, a fixed pressure board 15, and a conveyor belt 16 extending aboutthe conveyor rolls. A means is provided for adjusting the pressure board14 comprising shafts 17 and 18 each carrying a pair of cranks 19provided with arms 20 and 21. Each of the arms 20 is provided with anextending lug 22 adapted to abut the lower face 23 of the pressure boardfor retaining said board in adjusted positions relative to conveyor belt16. The pressure board is raised or lowered by simultaneously actuatingthe cranks 19 which are fixedly secured on shafts17' and 18. The

. lower ends of arms 21 are connected by means of a rod 24 havingpivotal mountings at 25 1928. Serial No. 276,304.

tatably supports conveyor roller 33 mounted on a shaft 34. An arm 35,bolted or otherwise secured upon arm 31, is provided at one end with anadjustable bearing block 36 in which is rotatably mounted a conveyorroller 37. A conveyor belt 38 extends about the conveyor rolls 33 and 37which are driven in a counter clockwise direction by. means of sprockets39 and 40 connected by chain 41. Sprocket 39 is rotatable with roller 33and sprocket 40 is rotatable with conveyor roller 12.' Rotatory motionis imparte to conveyor roller 12 by means of an idler gear 42 meshingwith gears 43- and 44 mounted on shaft 10 and drum 45-of a primarymolder, respectively. Idler gear 42 may be rotatably mounted in asuitable gear casing 420.

As indicated by arrow 46, the drum the primary molder rotates in a}counter clockwise direction. Said drum comprises a cylindrical rollingsurface 47 provided at each end with confining flanges 48 and 49. Aresilient arcuate pressure board 50 is disposed between the said flangesand spaced from the cylindrical member 47. Said pressure board isadapted to yieldingly apply pressure upon a mass of dough passingthrough the primary molder. At the upper end 51 of pressure board 50 ispivotally mounted a discharge sheet-52 upon-which dough is dischargedfrom the primary molder. Numeral 53 indicates a cylindricalmass of doughabout roller shaft 10. Idler gear 56 may be ro the end 54 thereof onto adischarge table 55.

In the modified form of the device disclosed in Fig. 3, there is shown aconveyor belt 55 which performs the same function as conveyor belt 38 ofthe embodiment shown in Fig. 1. The conveyor belt 55, however, requiresno separate driving means, said belt being driven by the frictionalcontact thereof upon conveyor belt 16 which latter is driven by means of-an'idler gear 56engaging a gear 57 rotatable with the drum of theprimary molder, and a gear 90 fixedly mounted upon tatably mounted in agear casing 91 secured, preferably to the auxiliary molder. Meanscomprising a screw 58 passing through a threaded bearing block 59 isutilized for adjusting the tension of belt 55. The cylindrical mass ofdough 53 is projected onto the pressure plate 14 in a manner similar tothat described in the first embodiment of the device.

The operation of the device is as follows.

In each embodiment of the'invention the auxiliary molder is disposedadjacent the primary molder and held in position by any suitable means,such as a connecting bar 60. 7

By this arrangement, the belts 55 and 38, of the device shown in Figs. 3and 1 respectively, are disposed in close proximity with the rollingsurface 47 of drum 49. As shown in the drawings, a mass of plastic doughis inserted between the rolling surface of the drum and pressure boardof the primary molder, wherein the mass of dough is formed into anelongated cylindrical body 53. As the body 53 is rolled between thepressure board and-rolling surface of the drum, it reaches the point 51,from whence it is discharged from the primary molder. Positive dischargeof the molded body is effected by means of the belts 38 and moving inthe direction indicated by the arrows. It is to be understood that inthe making of bread,

the various machines utilized are regulated or timed to operate onmasses of dough passing consecutively through the dough working machine.By means of the device of this invention positive discharge of themolded loaf from the primary molderto the second ing moving thedevice'toward and from its position relativeto the primary molder.

It is to be understood that various modifications may be made in thestructural details of the device, withoutdeparting from the spirit ofthe invention.

What is claimed is:

1. An auxiliary dough molder comprising a frame, a movable conveyormeans mounted on the frame, a pressure board mounted on the frame andspaced from the conveyor means, a support means on the frame, a conveyorroller rotatably mounted on the support means, and a conveyor beltpassing about the said conveyor roller and having frictional contactwith the first mentioned conveyor means, whereby movement of the firstmentioned conveyor means may be imparted to the second conveyor belt androller.

2. The combination with a primary dough molder comprising a drum andcooperative pressure board, an auxiliary dough molder for receiving andoperating upon partly molded loaves formed by the primary molder andcomprising a moving conveyor belt and cooperating pressure boards, ofmeans completely encircling the said conveyor belt for removing thepartly molded loaves from the primary molder and transferring saidloaves to the auxiliary molder.

3. The combination with a primary dough molder comprising a drum andcooperative pressure board, an auxiliary dough molder for receiving andoperating upon partly molded loaves formed by the primary molder andcomprising a moving conveyor belt and cooperating pressure boards, of asecond conveyor belt contacting the first mentioned conveyor belt andadapted for movement adjacent the primary molder drum for contacting thepartly molded loaf and positively directing it to the belt and pressureboard of the auxiliary molder.

4. In an auxiliary dough molder, the combination with a frame, of a pairof conveyor rolls rotatably mounted on the frame, an endless conveyorbelt passing about the rolls, a stationary and a movable pressure boardpositioned adjacent the conveyor belt and cooperating therewith forshaping dough loaves, a pair of extending arms on the frame, a conveyorroll rotatably supported on the arms, an endless conveyor belt passingabout the conveyor roll and the first mentioned conveyor belt wherebymotion of the first mentioned conveyor belt may be imparted to thesecond conveyor. belt, and means whereby the frame and conveyor meansmay be retained in position relative to a primary molder.
